Available in applications with a maximum normal operating temperatures of 85C and a second which is capable of operating at a maximum sustained temperature of 125C. Wide 120 view with 3-year warranty.

Omniguard 760 Multi-spectrum infra-red (IR) flame detector senses infrared radiation in five discreet infrared (IR5) wavelengths for early fire detection for maximum protection of people, machinery and facilities. Wide 90 view with 5-year warranty.

Omniguard 860 UV-IR is available in two versions; one for hydrocarbon fires only and one for hydocarbon and certain non-hydorcarbon fires. Responsive to hydrocarbon (gasoline, propane, methane, alcohol, JP-4, JP-3, etc). Also responsive to non-hydrocarbon (hydrogen, silane, hydrazine, etc) flames when special dual-pass IR sensor is used. Is able to distinguish between real fire and non-fire events, providing superior false alarm immunity. Wide 120 view with 3-year warranty.
